com.tangosol.coherence.commonj.WorkManager.AbstractWork

All Implemented Interfaces:

ExternalizableLite, PortableObject, Invocable, InvocableInOrder, PriorityTask, java.io.Serializable, java.lang.Runnable

Direct Known Subclasses:

WorkManager.ReleaseWork, WorkManager.RequestStatus, WorkManager.ScheduleWork, WorkManager.SendFeedback

Enclosing class:

WorkManager

protected abstract static class WorkManager.AbstractWork

extends AbstractInvocable

implements ExternalizableLite, PortableObject

Base class for Invocable tasks related to the WorkManager. Note, that aside of the ScheduleWork task all other tasks have to be scheduled immediately.

Field Summary

protected long	m_lWorkId The work id.
protected int	m_nMemberId The Work originator Member id.

Fields inherited from interface com.tangosol.net.PriorityTask

SCHEDULE_FIRST, SCHEDULE_IMMEDIATE, SCHEDULE_STANDARD, TIMEOUT_DEFAULT, TIMEOUT_NONE

Constructor Summary

WorkManager.AbstractWork()
Default constructor (necessary for a lite serialization).

WorkManager.AbstractWork(long lWorkId, int nMemberId)
Construct the AbstractWork to be executed on behalf of the specified member (a Work originator).

Method Summary

Member	getMember() Return a Work originator's Member object.
int	getMemberId() Return a Work originator's Member id.
int	getSchedulingPriority() Obtain this task's scheduling priority.
long	getWorkId() Return a Work id.
void	readExternal(java.io.DataInput in) Restore the contents of this object by loading the object's state from the passed DataInput object.
void	readExternal(PofReader in) Restore the contents of a user type instance by reading its state using the specified PofReader object.
void	writeExternal(java.io.DataOutput out) Save the contents of this object by storing the object's state into the passed DataOutput object.
void	writeExternal(PofWriter out) Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Constructor Detail

WorkManager.AbstractWork

public WorkManager.AbstractWork()

Default constructor (necessary for a lite serialization).

WorkManager.AbstractWork

public WorkManager.AbstractWork(long lWorkId,
                                int nMemberId)

Construct the AbstractWork to be executed on behalf of the specified member (a Work originator).

Parameters:

lWorkId - the Work id

nMemberId - the tagret Member id

Method Detail

getSchedulingPriority

public int getSchedulingPriority()

Obtain this task's scheduling priority. Valid values are one of the SCHEDULE_* constants.

This implementation returns SCHEDULE_STANDARD.

Specified by:

getSchedulingPriority in interface PriorityTask

Overrides:

getSchedulingPriority in class AbstractInvocable

Returns:

this task's scheduling priority

getWorkId

public long getWorkId()

Return a Work id.

Returns:

a Work id

getMemberId

public int getMemberId()

Return a Work originator's Member id.

Returns:

a Member id

getMember

public Member getMember()

Return a Work originator's Member object.

Returns:

a Member object or null

readExternal

public void readExternal(java.io.DataInput in)
                  throws java.io.IOException

Restore the contents of this object by loading the object's state from the passed DataInput object.

Specified by:

readExternal in interface ExternalizableLite

Parameters:

in - the DataInput stream to read data from in order to restore the state of this object

Throws:

java.io.IOException - if an I/O exception occurs

java.io.NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into

writeExternal

public void writeExternal(java.io.DataOutput out)
                   throws java.io.IOException

Save the contents of this object by storing the object's state into the passed DataOutput object.

Specified by:

writeExternal in interface ExternalizableLite

Parameters:

out - the DataOutput stream to write the state of this object to

Throws:

java.io.IOException - if an I/O exception occurs

readExternal

public void readExternal(PofReader in)
                  throws java.io.IOException

Restore the contents of a user type instance by reading its state using the specified PofReader object.

Specified by:

readExternal in interface PortableObject

Parameters:

in - the PofReader from which to read the object's state

Throws:

java.io.IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter out)
                   throws java.io.IOException

Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Specified by:

writeExternal in interface PortableObject

Parameters:

out - the PofWriter to which to write the object's state

Throws:

java.io.IOException - if an I/O error occurs
